Cyclotron Construction:
The cyclotron was built by workers of the Institute under the leadership of PhD Jerzy Schwabe and cooperation with specialists from Joint Institute For Nuclear Reaserch in Dubna and other institutes from Europe.

Main elements of cyclotron AIC-144:
1. Main Magnet. Gives constant magnet field.
2. Ion Source. Produce protons in center of acceleration chamber.
3. Ion beam acceleration system. Consist of accelerating electrode called dee and conjugated with RF generator.
4. Vacuum system. Pumping high vacuum in acceleration chamber and ion beam transport system.
5. Ion beam extraction system. Extract accelerated bunches of ions from cyclotron into ion beam transport system.
6. Ion beam transport system. Transporting ion beam from cyclotron to Hadron Therapy Room or External Production of Radioisotopes.
